Modeling and Simulation of Polymer Flooding with Time-Varying Injection Pressure.

Polymer flooding is one of the most incipient chemical-based enhanced oil recovery process that utilizes the injection of polymer solutions into oil reservoirs. The presence of a polymer in water increases the viscosity of the injected fluid, which upon injection reduces the water-to-oil mobility ratio and the permeability of the porous media, thereby improving oil recovery. The objective of this work is to investigate strategies that would help increase oil recovery.

Proteus syndrome and hypothyroidism. An unusual association.

We present a case of a 3½-year-old girl diagnosed as Proteus syndrome with severe cosmetic disfigurement-macrodactyly, hemi-hypertrophy of the face and limbs, megalencephaly, lymph edema of both hands and feet along with severe global developmental delay. She was found to have severe recalcitrant epilepsy and also primary hypothyroidism; the association of which is not mentioned in the previous literature.
